Single Degree of Freedom System-Video Simulation

[jrm2002]

Can anyone help me with some video simulations on vibrations in single degree of freedom system like the one in the link below

Just copy and paste in your address box--

You should be a bit more specific about what exactly your problem is.

For one thing, this is harmonic motion with one degree of freedom.

Also, the initial conditions are:

x(0) ~= 4.45m

$$\dot {x(0)} ~= 0.6 m/s$$

I do not like this demonstration. They should have their neutral axis about the equilibrium position, not at around 4.5. They need to do a coordinate transformation.

You can easily see that this is a single degree of freedom by applying Gruebler's equation.
